H2A.X is a 14 kD basal histone and a member of the H2 histone family. This nuclear protein is synthesized in the G1 and S phase of the cell cycle and is known to be important for recombination between immunoglobulin switch regions. H2A.X becomes phosphorylated on serine 139 after double-stranded DNA breaks. Phosphorylated H2A.X promotes DNA repair and maintains genomic stability. The Poly6133 antibody has been shown to be useful for Western blotting and immunofluorescence of human H2A.X.

FAQs for H2AX Antibody (NB100-78355). (Showing 1 - 1 of 1 FAQ).

  1. I am doing Western blot for H2AX using HL-60 cells, but I do not know which secondary antibody should I use, that is rabbit, mouse or goat?
    • Our lab recommends using a secondary that is appropriate to the primary antibody chosen for your Westerns. Therefore, if you decide to choose a Rabbit polyclonal anti-H2AX antibody, we would recommend an anti-Rabbit IgG secondary conjugated to HRP, or your specific detection system. The host of the secondary should not make a difference in your western blot assay.
